Globas - Noise and Vibration

Noise and vibration (NVH) is one of the product characteristics that can be easily sensed by people, and is therefore a high priority. It is a characteristic that designers of promising products often seek to improve in order to distinguish themselves from their competitors. Example of other tasks:

calculation of acoustic waves distribution from the source both over the surface of the structure and in the area of the acoustic field. Initial data (characteristics of the vibrating source) can be taken as a result of either experiment or finite element analysis;
calculation of acoustic dispersion as a result of reflection or diffraction from any structure in the acoustic field.
Obtaining the resulting acoustic field and vibration of the structure from an incident external sound wave;
analysis of the transformation of sound energy as a result of reflection, absorption and transmission through structural elements. Calculation of vibration levels both on the inside and on the outside of the sound-absorbing panels;
vibration transmission path analysis;
calculation of structure vibrations for a given force effect and subsequent calculation of the acoustic field generated by the vibrating structure
analysis of dynamic stability of systems to determine their propensity to increase in vibration amplitudes;
calculation of the contribution of individual sections of vibrating structures to the acoustic or structural response;
analysis of steady-state harmonic oscillations to obtain vibration and noise spectra.
